Information Technology Approaches To Forest Management, Mary Snow, Richard Snow Jan 2017

Information Technology Approaches To Forest Management, Mary Snow, Richard Snow

Publications

The majority of the world’s forests occur where there is a dry season long enough to affect a seasonal change in the forest community. The seasonal forest may include evergreen, semi-deciduous, deciduous trees, or some combination of these. Local differences in soil or other site characteristics often determine which community persists. Since the seasonal forests exist where there is seasonal precipitation, the character of the forest is closely associated with the length of the rainy season. As the length of the rainy season decreases, the density of the canopy decreases. If the global climate system warms and prolonged drought gives …


Agricultural Productivity Growth In Central America And The Caribbean, Ayako Ebata Dec 2011

Agricultural Productivity Growth In Central America And The Caribbean, Ayako Ebata

Department of Agricultural Economics: Dissertations, Theses, and Student Research

This thesis estimates total factor productivity (TFP) growth in the agricultural sector of fourteen regions in Central America and the Caribbean. First, TFP is measured parametrically and non-parametrically, using the Ordinary Least Square (OLS) method and the Maximum Likelihood (ML) method to estimate a translog production function and the Malmquist index approach. Secondly, the thesis incorporates an environmental bad, CO2 emissions from expansion of agricultural land by sacrificing forest area and estimates environmentally adjusted productivity (EAP) growth rates using an output distance function in order to assess how the growth of TFP rates changes when such a bad is …

Source Regions For Co2 At Cape Point Assessed By Modelling, 222rn And Meteorological Data, S. Whittlestone, E. Kowalczyk, E.-G Brunke, C. Labuschagne

Faculty of Science - Papers (Archive)

This study explores methods of characterising experimental and modelling data to see if trace gas measurements at the Cape Point GAW station could improve our understanding of sources from the continent. Selection criteria have been defined which make it possible to divide the samples into categories with predominant transport to Cape Point from one of four source regions: City (greater Cape Town); close rural (within about 150 km of Cape Point); distant rural (from 150 to about 500 km) and very distant rural covering the rest of southern Africa. For species with fairly uniform source such as radon or CO, …

Transcranial Doppler Estimation Of Cerebral Blood Flow And Cerebrovascular Conductance During Modified Rebreathing, Jurgen A.H.R. Claassen, Rong Zhang, Qi Fu, Sarah Witkowski, Benjamin D. Levine Mar 2007

Transcranial Doppler Estimation Of Cerebral Blood Flow And Cerebrovascular Conductance During Modified Rebreathing, Jurgen A.H.R. Claassen, Rong Zhang, Qi Fu, Sarah Witkowski, Benjamin D. Levine

Exercise and Sport Studies: Faculty Publications

Clinical transcranial Doppler assessment of cerebral vasomotor reactivity (CVMR) uses linear regression of cerebral blood flow velocity (CBFV) vs. end-tidal CO2 (PETCO2) under steady-state conditions. However, the cerebral blood flow (CBF)-PETCO2 relationship is nonlinear, even for moderate changes in CO2. Moreover, CBF is increased by increases in arterial blood pressure (ABP) during hypercapnia. We used a modified rebreathing protocol to estimate CVMR during transient breath-by-breath changes in CBFV and PETCO2. Ten healthy subjects (6 men) performed 15 s of hyperventilation followed by 5 min of rebreathing, with supplemental O2 to maintain arterial oxygen saturation constant. To minimize effects of changes …
